Apr 11, 2019 Xanthate Application in Copper Froth Flotation. In the flotation process of copper ore, xanthate mainly reacts with Cu2+. Therefore, when processing minerals containing Cu2+ on the surface, the effect of xanthate is stronger, and the order of its action is Cu2S CuS Cu5FeS4 CuFeS2. 4. Xanthate Application in Galena Froth Flotation.Apr 17, 2019 Embedded in a cloth of complicated Cu-Pb-Zn sulphide ore froth flotation process, the use of the potential regulation flotation technology of whole process priority, with lime slurry potential and adjustment to the LP - 01, SN - 9 + aniline aerofloat and butyl xanthate were collecting copper, lead, zinc, and use a combination of zinc sulfate.
An improvement in the froth flotation separation of metallic sulfide mineral ores, particularly those ores bearing copper and molybdenum, in which a mercaptan collector is used in an earlier primary flotation stage, the improvement comprising the addition of activated carbon to achieve deactivation of the mercaptan collector prior to the component mineral separation stage, thereby providing.Selectivity and power of frothers in copper ore flotation 519 Figures 1 and 2 show that the concentrate yield (Fig. 1) and copper recovery (Fig. 2) are dependent on the type and dose (concentration) of frother. Higher frother dose yielded higher mass and copper recoveries. The flotation.
About 80 of primary copper production comes from low-grade or poor sulfide ores. After enrichment steps, the copper concentrates are usually treated by pyrometallurgical methods. Generally, copper extraction follows the sequence (see Figure below) 1. Beneficiation by froth flotation of ore to give copper concentrate.Flotation is the most important and versatile mineral processing technique, with millions of tons of mixed solids processed daily to concentrate mineral values. Its applications range from relatively simple mineral separations such as sulphide ore concentration to complex systems such as copper-lead-zinc separation and fine coal beneficiation. Other uses of flotation include biochemical and.
Apr 25, 2017 Mining operations extract copper from the ground via open pit mines. Once the copper-containing earth is extracted, the extract is ground to fine ore and put through a froth flotation process. This process combines the ore with water and a collector chemical that makes copper hydrophobic (a condition which repels water).What I claim and desire to protect by letters patent is 1. In the process of separating copper and molybdenum minerals from their associated gangue by subjecting an aqueous pulp of porphyry copper ore to a froth flotation process in the pressence of a gangue depressant and recovering the separated minerals as a flotation froth concentrate, the improvement wherein the depressant is a water.
